COMBINATION-TOOL.

.Patented Nov. 9, i920.

Application filed March 18, 1920. Serial No. 366,815.

To all whom t may concern Be it known that I, ROYAL H.l DEA-N, a

Vcitizen of the United Stateaand a resident of Sioux City, in the county of Woodbury and State of Iowa, have invented a new and Improved Combination-Tool, of which the following is a full, clear, and exact description.

and is particularly adapted for use in connection with the valve and valve cage of the n type of Buick engine in general use.

.fi further object is to provide a tool which can be manipulated to remove `the valve cage on the engine cylinder, to raise the rocker arm and ,also to compress'the valve spring to permit a release of the pin in the valve stem holding the spring assembled thereon. l

I/Vith these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a perspective view of my improved tool;

Fig. 2 is a view showing the position of the tool when lifting the rocker arm;

Fig. 3 is a view showing the tool in position for pulling or withdrawing the valve cage from the engine cylinder; and

Fig. 4 is a similar view showing the tool in position to compress the valve spring.

My improved tool comprises four main parts; namely, a bar or lever 1, a fulcruming device 2, a bracket 3, and a hook 4. The bar or lever 1 is of any desired length and is provided at one end with a fork 5 which may be made of the desired thickness to perform the functions intended. n

The fulcruming device 2 is provided with a bifurcated end 6 straddling the bar 1 in rear of the fork 5 and pivotally connected to the bar 1 by a rivet 7. One end of the bracket 3 is pivotally connected to the bifurcated end 6 of the fulcruming device 2 by means of a rivet 8 and this bracket 3 at its free end is made with a supporting platform 9 having a web 10 on its under face and provided with a lip 11'at its free end.

VThe hook 4 is projected through an opening 12 in the bar or lever 1 and has a head 13 at its end preventing longitudinal movement of the hook yet permitting the hook to be swung to any position desired.

14 represents an engine cylinder and 15 a valve cage located in the cylinder and having a threaded nut 16 to secure the same in the cylinder. 17 is the valve located at the inner end of the cage and having a stem 13 projecting through the cage and at its upper end provided with a disk 20, with a pin 21 above the disk, and a coiled spring 22 hetween the disk 2O and the nut 16 normally holding the valve in closed position. 23 represents the rocker arm for engaging the stem 18 to operate the valve 17 and this rocker armis supported upon a post 24 as is customary in the art.

The engine structure above described is the common Buick structure in general use 4and my improved tool `is devised with a view of controlling the removal of the valve cage and the operation of the parts, as will hereinafter appear.

In Fig. 2, I show the position of my improved tool for exerting downward pressure on the rocker arm. In this position the hook 4 is engaged under the outer end of the rocker arm 23 and the bar or lever 1 is fulcrumed on the upper end of the post 24, so that an upward movement of the outer endV of the lever will operate to force the free end of the rocker arm downwardly.

In Fig. 3, I show the position of my improved tool for pulling out or withdrawing the valve cage from the engine cylinder. The

nut 16 is turned to release the cage from the engine cylinder and the forked end Y5 of the lever is located so as to straddle the valve stem 18 and is located between the convolutions of the spring 22. The fulcruming device 2 is in. upright position resting against the engine cylinder 14 so that when a downward pressure is applied to the outer or free end of the lever 1, the valve cage will be forced out of the engine cylinder.

Fig. 4 illustrates my improved tool in position to compress the spring 22 and allow the pin 21 to be removed. In this position the bracket 3 supports the cage 15 on its platform 9. The forked end 5 of the lever 1 straddles the valve stem 18 above the disk 20 s0 that when an upward pressure is applied to the outer end of the leverV 1, the

spring vvillbe compressed relieving pressure against the pin 21 to allovv the latter to be removed. When the tool is used for compressing the springi the platform 9 can be conveniently braced against any suitable support 25 and the web l0 provides a dovvndescribed Without departing` from the invention, a-nd hence l do not limit myself to the precise details set forth, but consider vmyself at Libertyto make such changes and alterations as fairly fall Within the spirit andvscope of the appended claims.

I claim.: i

1. A combination tool of thecharacter described, comprising a lever, a fork at one end of the lever, a fulcruining device havinga bifurcated end stra'didling the lever, and a bracket pivotally connected to said v bifurcated end.

2. A tool of the character described, comprising a lever, a forlkat one end of the lever, .a fulcrnming device having a Vbifurcated end straddling the lever and pivotally connected thereto, and a bracket pivotally connected -to the bifiircated end of the fulcifuming device.

3. A tool of the character described, comprising a lever, a fork at one end of the lever, a fulcruming devicehaving a bifurcated endv straddling the lever and pivotally connected thereto and having its extremities extending therebeyond` ay bracket pivotally connected to the extremities of said bifur- 'cated endV of the fulcrnming device, a plat- Vform Von the free end of said bracket, and

a lip at the free end of the platform.

a. tool ofthe character described, comprisinga lever, a forkat one 'end of the lever, a fulcrumingrde'vice having` a bifur-V cated end straddling the lever and pivotally connected thereto, a bracket `pivotally connected to the bifurcated end of the fulcruming device, a platformen the free end of said bracket, a lip at the free end of the platform, and a Web located under the plat` (form.

5. A tool ofthe character described, comprising a lever, a fork at one end of the lever, a hook pivotally connected to the lever adjacent its other end, a fulcruming vdevice pivotally connected to the .lever adjacent the fork` and `a bracket pivotally connected to the fnlcrnmiiig device.
